I noticed that FSB at 133MHz and memory at 133MHz has a higher memory bandwidth than FSB at 115MHz and memory at 148MHz. I guess the FSB speed has a big impact on the measured bandwidth. Is this actually true, or just for benchmark software?

The FSB is the speed the motherboard will run the memory at. If you have good memory, you can push the fsb higher. I have run my memory at 146Mhz. Of course, this speeds everything else up on the motherboard so you have to be careful.

Yeah, but what I mean is that memory speed has less impact on memory bandwidth than FSB. If you hold the memory speed constant and increase the FSB, you will see a much bigger increase in memory bandwidth than if you hold FSB constant and increase the memory speed.

Okay...your confusing with the terms "memory bandwidth" and "memory speed". Can you give me an example with numbers?

Oh, never mind. I just downloaded the new sandra and I'm getting completely different results, which coincide with my expectations. Maybe there was a bug in my other version of sandra.

Thanks for your reply.
